Undefeated Knicks claim top spot, Pacers plummet in Power Rankings

It seems everything comes in a Big Three in the NBA these days, so it's no surprise the top of this week's Power Rankings feature a new version of just that. The Heat, Lakers and Thunder led everyone's list of title hopefuls going into the season -- and still might -- but the Knicks, Clippers and Grizzlies have outplayed the preseason darlings. While Miami hasn't shown much cause for concern, the Lakers' struggles are well-documented and the Thunder have been less fluid than in years past. Meanwhile, the Knicks have a chance to match their best start in franchise history Friday night and the Clippers and Grizzlies have combined to go 4-0 against the preseason's power trio.

But the Richter-rocking movement wasn't just among the league's elite this week. The Pacers, ranked No. 9 in the preseson rankings, have fallen out of the top 20. The Bobcats, losers of 23 straight games to end the 2011-12 season, have skyrocketed 10 spots to No. 18 after a head-turning 4-3 start.

Needless to say, it's been another week of surprises. So without further ado, let's see where all 30 NBA teams stack up.
